How to check number of zeros in an array?

Eg: I have a vector A = [0,0,4,3] and B = [0,1,2,3,4] and C = [0,0,0,0,0] and D = [0,1,2,0,0]

SO THE OUTPUT SHOULD CONTAIN NUMBER OF ZEROS IN EACH VECTOR:

A = 2

B = 1

C = 5

D = 3

Answer 1

[Paolo]

 A = nnz(~A)
 B = nnz(~B)
 C = nnz(~C)
 D = nnz(~D)

I doubt that it gets much more compact than that!

Answer 2

[Raul Andres Lopez Romero]

Try this:

    nzeros=numel(A)-nnz(A)

numel(X) give you the number of elements in an array, nnz(X) give you the numbers of Non zero elements in an array.

try it for every array you have.
